What Color Buttercream For Edible Images?

I'm doing my first edible images this weekend and they're whoppers! I'm make an 8-inch cube cake and it'll look like a photo cube, so I'll have five 8-in. square images. The photos will be on the darkish side like the one I've attached here. Should I use just a plain white buttercream? Will it show through the image? I'm sure when I actually get the images and start playing with them, it'll be more clear, but I'm trying to plan how it'll work.

I'm going to put black fondant strips around the edges to kind of frame the photos and figured I'd do that after the images have set. Do I just lightly brush the back of the fondant strips with water like I normally would to attach them to buttercream?

You always want to use white behind edible images, Any other color will bleed through and ruin your picture. Trust me, I learned this one the hard way. I'm not sure about the water on the fondant with the edible image. Hopefully someone else has had experience with this, and can help you more. Sounds like a really cool cake. I can't wait to see it!

Now, if CakeCentral will start acting right and send me notifications of postings, I'd be a totally happy camper. Everything on my end is as it should be, but I haven't received a notification for a post in a couple of days. Maybe I'll log off and and log back in to CC and see if that helps.

I found that if the background of you EI is very dark and you use almost the same color icing under it its fine . I posted a st patricks day cake where I did that and it never showed through at all . Even after min of 24 hrs ! Just a thought !

Thanks, Renee, for showing me that. The cake was still cute, but you can see through the edible image. It's going to be white buttercream all the way for me and I hope it doesn't make the dark parts of the photos too light.
